Uneven security review
Core software from major open source projects gets sustained scrutiny. Individual plugins, especially free ones from small or single-maintainer teams, often don't, and a large share of real-world WordPress, Drupal, and Joomla security incidents trace back to plugins rather than core.
The WikiSuite / Tiki approach
Tiki, the content-and-collaboration engine behind WikiSuite, takes the opposite approach: features like forums, file galleries, calendars, wiki pages, and structured data trackers are built into the core and maintained by the same team, under the same release and security process, rather than bolted on as separate plugins.
That means:
One upgrade path, not a dozen independently-versioned dependencies to track and test.
One security review process instead of trusting the weakest plugin on the site.
Features that are designed to work together from the start, not patched to tolerate each other.
